I hadn't seen this yet: Destiny missions to be reordered (Destiny)

That sounds like a good idea. Imagine if you had just done the Black Garden storyline missions only, in order, then finished the game. You'd now have all these side missions to do, and it would have alleviated the problem of having nothing to do at level 20. So you've beaten the game and you are level 20. Instead of having nothing new to do, you now have all the side missions to explore. This works out because your main narrative is 'done', and now it's just flavor and exploration. Doing the side missions always feels out of place while your narrative is going. If there is such an urgency to destroy the heart, why am I worrying about killing the Archon priest, or the Archon of the House of Winter, or Valus D'aruc?

A much better setup would have been having all the strikes and side missions open up when you hit level 20. Maybe that's what they are doing.
